FEED S. CARE, OF NEWTON, MASSACHUSETTS, ASSIGNOR TO CARR FASTENER COMPANY, OF CAMBRIDGE, MIASSACHUSETTS,

SEPARABLE Application filed March 8,

T0 @ZZ @0710? it may cancer Be it known that I, Faun CARR, a citizen of the United States, and a resident of Newton, in the county of Middlesex, State of lilassaehusett-s, have invented an Improvement in Separable Fasteners, of which the following description. in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention pertains to improvements in separable fasteners, and more particularly, though not exclusively, to separable fasteners adapted to be secured to carrying fabrics by metallic securing" means, such, for instance, as those ordinarily used in connection with glove fasteners and the like. It is among the objects of the invention to provide a fastener of superior holding power, and simple and rugged construction, where-- in the socket element may be conveniently secured. in a predetermined relationship to its carrying fabric by a socket-attaching tool.

in the drawings, which show preferred form of one illustrative embodiment of my invention Figure l a front elevation showing a preferred form of stud and socket attached to their carrying" fabrics 7 7 $2 is a section on the line 2--:2 of l ig. l; and

Fio IS a section on the line Zl-5 of Referring to the drawings and to the preferred form of my invention selected for ilh ."atire purposes. I have shown a stud of the usual type incl udinpa head i: and a neck 5, and secured to the stud-carrying fabric 6 by a. stud attaching; rivet 7. The preferred. form of socket illustrated includes a casino; 8 containing a spring 9 and providing an outer flange i0 and an extension llv adapted to pass through the socket-carrying fabric 153 and to he clinched within. a socket securing cap 13. The spring 9 may be of the type illustrated in my co-pending application filed herewith, Serial No. 4.505%, and. may cooperate with the stud to provide a lateral lock in the general manner described in said CO-PBIlCliHg application. The spring 9 may be provided with a. locating;- notch 20 A CORPORATION OF MAINE.

on that side of the spring wherein the slitor slot 21 located, this being, in the type of spring illustrated, the wider portion of the annulus forming the spring. As in the co-pending application above referred to, means: are. provided for spacing the narrower side of the spring; from the casing. the spacing means preferably, as illustrated. taking the form of projections 22, 22 thrown up from the front flange and adapted to engage faces 23, 23 on the springs so that lateral strain between stud and socket in the iilirection indicated by the arrow in l ig. 5% may tend to close the spring and incre; se the grip on the stud in the genenl manner described in the co -pending application above referred to. The notch is, however, prefierably distinct from the slit 21 in the spring.

While I have shown and described a preferred form of one embodiment of my invention, it will he understood that changes involvino omission, substitution, alteration and reversal of parts, and'even changes in the mode of operation, may be made without departing from the scope of my invention, which is best defined in the following claims.

Claims.

1,. A socket for eluding a casing, said casing iaving said spring generally annular in peripheral shape but the annulus wider at one side of the studreceiving aperture than at the opposite side thereof. said annulus split at the wider side thereof, means for spacing),- the arrower side of the spring from said casing and a locating; notch communicating with the stud-receiving aperture but distinct from the slit in the spring, saidnotch in the wider portion of said spring.

A. socket for separable fasteners including a casing and a. spring); in said casing, said casin presenting spring retaining flange-s at each side of the s; ng and an extension fromone of said flanges for securing separable fasteners insheet metal spring in stud-receivin opening.

the socket to its carrying fabric, the flange opposite said extension having projections engaging said spring to space said spring away from one side of said casing.

In testimony whereof, I have signed my name to this specification.
